IMPROVEMENT lN WAGON-BRAKE SHOES.

Specification forming part of Letters Patent No. 194,118, dated August 14, 1877; application filed June 30, 1877.

To all whom it may concern:

Be it known that I, INDEPENDENCE E. S. ALEXANDER, of Henry, in the county of Henry and State of Tennessee, have invented a new and Improved Wagon-Brake, of which pressure, and thatwill not wear the face of the tire.

In the drawing, A is the frame or basepiece, upon which ears b are formed, two at each end. B Bare curved levers, on each of which a shoulder, 0, is formed. These levers are pivoted between the ears I), and are cut away at their sides from their shoulders c to their free ends, so that their sides overlap. A spring, (1, issecured to the base'piece A, and presses the ends of the levers B outward.

The base-piece A is secured to the brakebar, by means of one or more bolts, in a position to receive the tire of the wagon-wheel between the shoulders c.

When itis desired to retard or stop the wheel, pressure is applied to the brake-bar in the usual Way, when the free ends of the levers B, being forced back by contact with the face of the tire, clamp the edges of the tire between the shoulders 0. The spring (1 throws the levers outward and releases the tire when pressure is removed from the brake-lever.

Shoulders c are formed on the levers B, which strike the base-piece, and prevent the levers from being thrown too far outward by the spring.

Having thus described my invention, I

claim as new and desire to secure by Letters.

Patent- In a wagon-brake, the combination, with frame A, having ears b and spring d, of the curved levers B B, cut away from shoulders c to their free ends, and thus allowing their sides to overlap, as and for the purpose specified. Y

INDEPENDENCE E. S. ALEXANDER.
